คุณลักษณะ

• Easy and quick welding installation is possible.
• The tension spring supports the ring in the desired position and reduces noise. (1, 5 t to 10 t)
• DIN5688 compliant, quality grade 100, 80, and all magnetic flaw inspection passed.
• Spacers (approximately 3 mm) act as voids for root welding.
• The placement of the weld seam (HV through type) enables you to initiate the requirements of DIN18800. In other words, since the joints are completely shielded, there is no risk of a corrosion layer, so it can be used outdoors.
